I have not but you certainly can do it. The length of the tube will determine
the peak resonant frequency and you would have to experiment with the length to
tune it to the pitch you like best to listen to.
Remember the days you would blow across a bottle to make a tone? The more you
drank out of the bottle the lower the pitch.
I like this project and I am going to build one and it will be with a straight
tube mounted on a little stand so it aims towards me.

Might be an interesting experiment.
The 45 deg long radius street elbow in 2" is an order only item in my area so
thought I'd substitute a straight length.
